Refrigeration system



March 24, 1931 F. F. BRUECKNER i REFRIGERATION SYSTEM Filed April l2, 1926 2 Sheets-Sheet l Patented Mar. 2,4, 193i UNITED STATES- PATENT OFFICE FRED F. BR'UECKNER, 0F DETROIT, MICHIGAN, ASSIGNOR T0 COPELAIND PRODUCTS, INC., OF DETROIT, MICHIGAN, A CORPORATION OF'MICHIGAN BEFRIGERATION SYSTEM Application led April 12, 1926. Serial No. 101,278.

It is the primary object of my invention to ovide a refrigeration system wherein the liat absorbing device and the heat dissipating device are mounted on a common movable support,and are separated by a fixed thermally insulated wall, so that the same may be placed in and removed from a ref rigerating cabinet as a unit.l This construction 1s particularly useful from the standpoint of ser v 1o icing systems in use, for the reason that in the event of a diliculty being experienced with the refrigeration system, a service man may call and remove the system fromthe refrigerating cabinet and replace 1t with an.- other like system which is in good repair, taking the system whichis to be repaired to. his place of business, where the repairs are made y experienced workmen, and with the propertools for the purpose available. In the mean time, the householder has not been deprived ofthe use of a refrigeration system in his cabinet during the repair period. 0

With the above and-other objects 1n view, my invention consists in the arrangement, combination and construction of the various parts of my improved device as described in my specification, claimed in m sh`own in the accompanying which:

Fig. 1 is an elevation of a refrigerating cabinet, embodying my invention.

Fig. 2 is a vertical section through the same, illustrating the connectionbetween the heat absorbing and heat dissipating portions ofthe system.

Fig. 3 is a horizontal section taken 3-3 ofFig. 2 looking downward.

Fig. 4 is a vertical section through the upper part of the cabinet closely ad]acent to and arallel to partition. 30.

I ave shown a refrigerating cabinet, designated generally as 5, having a chamber 6 adapted to-receive the heat dissipating portion of a refri eratin `system, a chamber` 7 ada ted to receive the eat absorbin portion of t e system, and the chambers 8 an 9 adapted to receive the articles of food. The chamber 6 is closed at the front by a louvered door 10 adapted to swing on hinges 11; the chamber 7 is adapted to be closed by the door 12 rawings, in

on line claim, and' swinging on the hinges 13; and the chambers 8 and 9 are adapted to be closed-by the doors 14 and l5 swinging on the hinges 16 and 17, respectively. i

-The heat absorbing portion of the mechanism ma)7 comprise a conventional brine tank 18 having a conventional expansion chamber or expansion coils therein (not shown), and` connected by the pipes 19 and 20 with the coils 21 and compressor 22, respectively, of the heat dissipating portion of the system. The condensing coils 21 and a conventional motor 23 are secured as at 24 and 25, respectively, to the base or support 26. The compressor 22 is mounted on legs 28 secured to the base 26 as at 27. The brine tank 18 is secured to the base 26 as by angle brackets 29.

A thermally insulated partition 30 is interposed betweensthe chambers 6 and 7, said partition having a slot 31 cut therein through which' the base 26 extends, the said base being v slidably mounted in grooves or channels provided in the members 32 and 33 in the chambers 6 and 7, respectively. Suitably insulating strips 34 may beprovided between the faces of the base 26 and the edges of the slot 31, so as to prevent transfer of heat and cold through the slot when the base is in place.

The front of the refri erator 5 which consists of a'striker plate or the doors 10 and 12, is designated as at 35, and is removably secured `in place by a plurality of screws 36.

It will be apparent that in order to remove the refrigerating unit from the cabinet, it is only necessary to remove the screws 3 6 and the plate 35, at the same time opening the doors 10 and 12, and thenI slide the entire system from the cabinet by removing the base .26. Another like system can lthen be inserted" inthe cabinet-, the late i6-replaced and the doors 10 and'v 12 yc osed. 'Provision `for the pipes 19 and 20 connecting the chambers 6 and 7 and likewise connecting the heat absorbing and heat dissipating portions of the system is made by the groove 37 inthe removable plate 35. y

It will be obvious that my improved construction has decided advantages over systems, wherein the heat dissipating apparatus is removable as a unit, for the reason that the connection'between the heat dissipatingand heat absorbing portions of the system need not be broken.

It will likewise be obvious'fthat the part-icular type of system utilized with my invention is of no particular moment, and that various types maybe utilized with equal SUCCESS.

It will be obvious that various changes may be made in the arrangement, combination and construction of the various parts of my improved device without departing from the spirit of myinvention, and it is my intention to cover by my claim such changes as may be reasonably included Within the scope thereof.

What I claim is:

The combination of a refrigerator cabinet having an insulated cold storage compartment in its lower portion and one side of its upper portion and a ventilated machinery compartment in the other side of its upper portion, and an air cooled mechanical refrigerating apparatus comprising a heat absorbing unit and a heat dlssipating unit operatively interconnected and mounted upon a common support at substantially the same level, said refrigerating apparatus being disposed in said cabinet with said heat absorbing unit in that part of the cold storage compartment which comprises one side ofthe u per portion of said cabinet and with the air cooled heat dissipating unit in the ventilated lmachinery compartment which comprises the other side of the upper portion of said cabinet, said common support for said a paratus and said connections between said ieat absorbing and vheat dissipating units passing through openings rin the insulated walls between said machinery compartment and said f cold storage compartment provided with means for preventing heat leakage around said su port and said connections, whereby said re rigerating apparatus is contained entirely within said cabinet and is so arranged that the heat given off by said 'heat dissipating apparatus will naturallymove awa from said cold stora e compartment and t e circulation of coldg air currents within said cold storage compartment will circulate in a. natural path around said heat absorbing unit.
